There is sometimes a situation in which one needs to get the relative offset of a structure field, common examples of this include serialization frameworks which aid to serialize objects, vertex attributes for rendering (D3D, GL.), etc.
The most common technique for getting this information is through the offsetof
macro defined in stddef.h. Unfortunately using the macro in C++ comes with a
new set of restrictions that prevent some (subjectively valid) uses of it.
